ntfs-3g is still beta, and has to be compiled from source. But the steps are quite simple. The details are here, and the instructions are quite clear:

Note that ntfsmount (which comes with knoppix 5.01) and ntfs-3g are user-space filesystems, and you don't mount the ntfs partition with a normal "mount" command -- you use "ntfsmount" and "ntfs-3g"

Further test results:

- I installed mozilla onto ntfs partition and ran off it. Surfing images via google image search - no problems.

- Copied huge file of 2GB to ntfs. A bit slow but not really noticeable. Otherwise ok. I don't have files bigger than 2GB -- will try something bigger next time.
- Copied UNIONFS/usr to ntfs. This is a huge directory tree with about 74 thousand files total about 1+ GB. No problems.
- Deleted all the files copied. No problems.
- Occasionally, when copying, there is a warning "Could not change file permissions...." I will ask the developers what this is about. But it doesn't affect the copying.
- Haven't tried the bittorrent download yet.

Been running the ntfs partition with Knoppix the whole day, checking back and forth with XP, so far no problems except for the warning above.
